Crushing, screening and materials handling solutions company Pilot Crushtec has supplied one of its biggest semimobile modular jaw crushers to HCI Khusela Coal for use at its Palesa coal mine, in Bronkhorslspruit.

Pilot Crushtec sales director Graham Kleinhans, says that, while the brutish 42-1 Pilot Modular Trio MJ3254 is not the biggest crusher in the company’s range, it is the first one sold by the company in South Africa.

He explains that the jaw crusher, which can handle raw feed material of up to 650 mm in size. is the primary crusher for a plant at the mine and will feed coal that is smaller than 200 mm into a secondary roller crusher.

Palesa mine engineer Theo Ferreira says that the company acquired the large jaw crusher as it is able to handle the oversized feed material.

The jaw crusher is sold ready to install, is mounted on a heavv duty skid frame and is equipped with a vibrating grizzly feeder to ensure optimum feed at all times by removing undersized material.

It has a hydraulically adjustable jaw crusher, which enables it to process large quantities of material.

Ferreira explains that it has been a significant challenge for the plant’s existing roller crushers to compress material that is larger than 350 mm.

The throughput ol the Pilot Modular Trio MJ3254 has also impressed HCI Khusela Coal.

“Our throughput requirement was 600 t/h; however, this machine effortlessly exceeds this and is able lo reach up to 650 t/h.

“The throughput is dependent on the amount of coal received from the mine and. when the blasted coal particles are smaller, the throughput increases.” he explains.

Ferreira adds that the crusher has been adapted for the mine’s 525-V circuit and the machine’s simple assembly processes contributed to an effortless installation.

“The jaw crusher oilers an economical solution to our primary coal crushing requirements and we are pleased with the results ol the crusher since it was installed in June.

“However. Pilot Crushtec will conduct regular inspections to ensure that it operates at optimum performance consistently.” he concludes.
